It never fails. Sunday rolls around and all you want is some Chick-Fil-A. Except the restaurant chain is closed on Sundays.

However, this past Sunday, the chain made a rare exception – and for all the right reasons.

Several locations across Texas opened to help people impacted by deadly tornadoes that killed as many as 11 people near Dallas, according to AL. com.

"The locations were not open to the public, but team members from various restaurants in the area did volunteer to prepare and distribute free food to responders and others affected by the tornadoes—serving those in need during this tragic event," said Amanda Hannah, a spokeswoman for the chain, told CNBC.

Volunteers delivered the free sandwiches to first responders and victims of the storms, AL.com reported.

Chick-fil-A has maintained its rare Sunday closure policy since the chicken chain opened. The weekly day off is meant to encourage employees to rest, spend time with family and worship if they chose, CNBC reported.

This morning Chick-fil-A is breaking their own rule and cooking on a Sunday. For the best reason possible, to help feed those first responders and people in need affected by last night's tornadoes.
